Description

[Detailed description of the invention] This invention relates to a portable container such as a compact for storing cosmetics, etc. Specifically, it is used to store contents that require airtightness or fluid contents. The present invention relates to a suitable portable container.

Various portable containers of this type have been proposed in the past, one of which is known as shown in FIG. A convex ring 3 is provided in an upright manner on the upper surface of the peripheral edge of the cosmetic storage recess 2 of the main body 1, and has an inner diameter larger than the outer diameter of the convex ring 3 and an outer diameter that can be fitted into the lid body 4. A holding inner frame 6 is interposed between the main body 1 and the lid body 4 via a hinge 5 so as to be openable and closable, and a film 7 is further stretched over the inner frame 6. As a result, the lid body 4
When it is closed, the cosmetic storage recess 2 is sealed with a film 7 to provide airtightness.

However, with such a structure, the inner frame 6 is simply pressed with the lid 4 by the force of closing the lid 4, and therefore sufficient airtightness and liquid tightness cannot be obtained. There was a problem. In particular, since the middle frame 6 is formed into a ring shape as shown in the figure, it is easily distorted as a whole, and this has the disadvantage that the film 7 is not evenly pressed against the upper surface of the convex ring 3.

In addition, recently, many two-tiered portable containers with storage recesses on the top and bottom have been proposed.
It has been impossible to apply the prior art techniques described above to this type of container.

The present invention was developed in consideration of the above points, and has two storage recesses, upper and lower, and has a structure that effectively combines the storage recesses with geometric elements to ensure airtightness. The purpose of the present invention is to provide a portable container that can be made liquid-tight and easy to manufacture with a small number of parts.

Hereinafter, the present invention will be explained with reference to an embodiment shown in the attached FIGS. 2 to 5.

In the figure, reference numeral 10 is a container body, and this container body 10 has a bottom plate 11 and a peripheral wall 12, and is formed into a rectangular box shape as a whole. Container body 1
0 is fitted with an inner frame 15 having a cylindrical portion 14 for forming a circular storage recess 13 in the center thereof. The upper inner circumferential surface of the storage recess 13 is formed into an inclined surface 16 that slopes downward toward the center of the storage recess 13 .

A partition plate 20 for opening and closing the storage recess 13 and a lid body 30 are hingedly connected to the rear wall portion of the container body 10 via one hinge A. An auxiliary storage recess 21 whose bottom and peripheral wall protrude toward the container body 10 is formed in the partition plate 20, and the bottom outer peripheral surface of the auxiliary storage recess 21 is airtight and liquid-tight with respect to the inclined surface 16. It is formed on a tapered surface 22 that makes close surface contact. In order to make the storage recess 13 more air-tight and liquid-tight, the partition plate 20 has some elasticity in the entire partition plate 20 or only the auxiliary storage recess 21 in the embodiment. It is made of a material with properties such as polyolefin resin, thermoplastic elastomer, etc.

On the other hand, an annular protrusion 31 is formed on the inner surface of the lid 30 to press the tapered surface 22 into close contact with the inclined surface 16 when the lid 30 is in the closed position. That is, this annular protrusion 31 is
As shown in FIG. 5, its inner and outer diameters are larger than the inner diameter of the storage recess 13 and smaller than the inner diameter of the upper peripheral edge of the inclined surface 16.
0 is set to a protrusion length l that allows the peripheral edge of the tip of the annular protrusion 31 to uniformly press the inside of the tapered surface 22 of the auxiliary storage recess 21 in the closed state.

Reference numeral 40 indicates that the free end of the lid 30 is connected to the container body 10.
This fastening member 40 is formed with a horizontal part 41 and a vertical part 42 to have an approximately inverted L-shape in cross section, and the inner surface of the vertical part 42 is provided with a hook 17 of the container body 10. Hook 43 to engage
is provided. Further, the horizontal portion 41 is connected to the lid body 30.
For the fitting recess 32 provided at the center of the free end of
The horizontal portion 41 is attached to be rotatable vertically around protruding shafts 44 at both ends. Between the inner surface of the horizontal portion 41 and the bottom surface of the fitting recess 32, the entire stopper member 40 is inserted into a fourth
A spring 45 is set which biases counterclockwise in the figure. Furthermore, a stepped portion 4 is provided at the tip edge of the horizontal portion 41.
6 is formed, and this stepped portion 46 engages with the upper edge 33 of the fitting recess 32, thereby restricting the counterclockwise rotation of the stop member 40. Note that reference numeral 47 is a recessed portion for positioning the spring 45 in a fixed position.

In the portable container configured as above,
When the lid body 30 is closed, the hook 43 of the stopper member 40
and the hook 17 of the container body 10 are engaged, and the lid body 3 is closed.
0 is temporarily fixed to the container body 10. At this time, the tapered surface 22, which is the bottom outer peripheral surface of the auxiliary storage recess 21 of the partition plate 20, comes into surface contact with the inclined surface 16 as shown in FIG.
1 presses the tapered surface 22 from inside the auxiliary storage recess 21 in a direction that presses the tapered surface 22 against the inclined surface 16, so that the tapered surface 22 comes into strong contact with the sloped surface 16, and as a result, the storage recess 13 Air-tightness or liquid-tightness becomes more reliable. Here, divider plate 2
0 or only the auxiliary storage recess 21 is made of a slightly elastic material.
The airtightness or liquidtightness described above becomes even more effective.

Furthermore, the storage recess 13 has a structure that can be sealed by effectively combining the shape elements without providing a seal ring, so the number of parts required for sealing does not increase. Therefore, it is easy to manufacture and assemble.

Note that the stopper member 40 shown in the embodiment is
Any other structure may be used as long as it can be temporarily fixed relatively firmly to the container body 10, and if necessary, a mirror or the like may be provided within the annular protrusion 31.

As described in detail above, according to the present invention, the structure has two storage recesses, upper and lower, and the storage recesses are effectively combined using geometrical elements, thereby ensuring reliable airtightness and liquid leakage. It has excellent effects such as being able to provide tightness, and being easy to manufacture and assemble due to the small number of parts.

In particular, according to the present invention, when the lid is closed,
The tip periphery of the annular protrusion uniformly presses the tapered surface from within the auxiliary storage recess in a direction that presses the tapered surface against the sloped surface, so the tapered surface adheres strongly and uniformly to the sloped surface, and as a result, the storage recess The air-tightness or liquid-tightness of the product becomes more reliable. In this case, especially
The annular protrusion is formed to be larger than the inner diameter of the storage recess and smaller than the inner diameter of the upper peripheral edge of the inclined surface, and is configured to be able to press substantially the middle portion of the tapered surface. The adhesion between the surfaces and the inclined surfaces becomes extremely excellent. In addition, because the partition plate is hinged to the container body by the same hinge as the lid, the partition plate and the lid plate are not consistent with each other and with the container body in their closed positions. Therefore, from this point of view as well, the tapered surface and the inclined surface come into close contact with each other to improve the sealing performance of the storage recess. Furthermore, an auxiliary storage recess with a peripheral wall protruding toward the container body is formed in the partition plate itself, and the bottom outer circumferential surface of the auxiliary storage recess is formed into a tapered surface that makes surface contact with the inclined surface. Therefore, the tapered surface part that is brought into close contact with the inclined surface has a structure that is difficult to deform into an elliptical or twisted shape as a whole due to the reinforcing action of other parts, and therefore, from this structure, more reliable sealing is achieved. Unique effects can be obtained, such as contributing to the effects of obtaining.
